APPARATUS FOR SUPPLYING AERATED LIQUIDS FROM BULK ON DRAFT.

SPECIFICATION forming part of Letters Patent No. 721,073, dated February17, 1903. I

Application filed May 27, 1901.

To all whom it may concern:

Be it known that I, WILLIAM NIOHOLLS, a subject of the'King of GreatBritain and Ireland, residing at 8 Barnards Inn, I-Iolborn, London,England, have invented certain new and useful Improvements in Apparatusfor Supplying Aerated Liquids from Bulk on Draft; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention for improvements in apparatus for supplying aeratedliquids from bulk on draft relates to apparatus in which the aeratedliquid is stored in a reservoir at a high. pressure and fromwhichreservoir any desired quantity can be drawn ofi into a measuringvessel and when the measuring vessel is shut off from the reservoir itscontents can be discharged. Apparatus of this class consists ofareservoir for containing aerated liquid under pressure, a measuringvessel, a controlling-valve governing the supply of aerated liquid fromthe reservoir to themeasuring vessel and an atmospheric communication atthe top of the measuring vessel, and an automatic valve closing theoutlet from the measuring vessel operated by the pressure in the vessel.In operation the operating-valve is operated to close the atmosphericcommunication to the top of the measuring vessel and open the supply tothe reservoir of aerated water. The aerated water enters the measuringvessel, and the pressure closes the automatic outlet valve. When theoperating valve is again returned to its initial position,

the reservoir of aerated liquid is cut off from the measuring vessel andthe communication of the top of the vessel with the atmosphere isopened. The aerated liquid in the measuring vessel is thus snifted andthen the automatic valve automatically opens the outlet, so that thecontents flow quietly out from the vessel. It will readily be seen thatfor the practical success of such an apparatus the controlling-valveshall be gas-tight and shall be movable only between its two operativepositions, so that it shall be impossible that the aerated liquid can bedischarged under pressure.

In carrying out this invention the above ed according to this invention..vertioal section taken at right angles to Fig.

onto thevalve-body. The top of the sleeve projects through the nut and apart of the projection is cut away. An operating-handle fixed onthelvalve-spindle Works between the stops formed by the above cut-awaypart. The stop insures that the aerated liquid shall be drawn offquietly.

In the accompanying drawings, Figure 1 is a vertical sectionof theapparatus construct- Fig. 2 is a 1. Fig. 3'is a cross-section of thevalve-body on theline A A, Fig. 2, showing the valve Fig. 4 is a similarcrosssection with the valve removed. Figs. 5 and 6 are plan and invertedplan, respectively, of the valve. Fig. 7 is a detail plan of theoperating handle and spindle and sleeve in -which the spindle works.

An arm or bracket 01, supports the valve body 0 and measuring vessel cland incloses a pipe I), communicating with the valve-chamber c and withav reservoir containing aerated liquid at a high pressure. Theface-valve 0 within the valve-chamber 0 controls the passage of theaerated liquid to the measuring vessel (1 and also the escape of the gastherefrom.- The said valve rests on a seating c and is rotated by thehorns e, which project from the spindle e, carrying the operatinghandle6 and engage freely in notches c in the valve. The spindle 6 passesthrough a sleeve m, and a collar on the spindle bears against thepacking e in the sleeve. The sleeve fits in the end of the valve-body cand is prevented from rotating in the valve-body by the key or featherm. Thecap-nut m screwing onto the end of the valve-body c, bears on anexternal collar on the sleeve and keeps the sleeve in place axially. Apacking is interposed between the top of the valvebody and the collar ofthe sleeve. The upper end of the sleeve m projects through the capnutand is cut away between the points wa m and a stop m on the handle 6works between the points m m. The valve is held down upon its seating cand the valve-spindle up against its seating c by the compressionspringe and by the pressure of the liquid.

Connected to the valve-body and centrally under the valve-seating is atubef, that passes down through the measuring-vessel (l and in whichworks a hollow piston and piston-rod f, supported in their normal raisedposition by the spring f and provided with perforations f at its bottom.The spindle f passes through the hollow piston-rod and is provided atits top end with a valve f, adapted to open and close the annularpassage between the piston-rod and spindle f and at its lower end with aplug or stopper f adapted to close the spout orifice or outlet (1 fromthe measuring vessel (1, as is shown in Fig. 2.

The measuring vessel (1 comprises an openended glass cylinder d heldbetween the ends (1 d of the metal cage d The hole 0 in the valve-seatcommunicates with the top of the measuring vessel. The hole a in thevalveseat communicates with the pipe b that opens out into the arm orbracket a, and is thus in communication with the atmosphere. The hole 0in the valve-seat communicates with the central passage 0 through thevalveseat, and thus with the tube f. The valve is recessed at its centerand is provided with the recess 0 in its face and with the hole apassing completely through it and always containing aerated liquid underpressure.

In Fig. l the various parts are shown in their normal positions with thestop m of the handle against the edge m the measuring vessel d beingopened to the atmosphere at the spout d, and through the hole 0 in thevalve-seat the recess 0 in the face of the valve and the hole 0 in thevalve-seat communicating with the space in the arm or bracket a,surrounding the supply-pipe b, the inlet 0 being opposite a solidportion of the valve-seating, so that the high-pressure liquid in thechamber 0' is out 01f from the central chamber a, and thus from themeasuring vessel d. In Fig. 3 the valve is shown in the same position asin Fig. 1. Upon turning the handle 6 and with it the valve 0 to theposition shown in Fig. 2, with the stop m against the edge m the recessa in the valve is removed from the holes a and c and the inlet 0 isbrought over the hole 0 in the valve-seat communicating with the centralchamber a. The high-pressure liquid entering the chamber 0 drives downthe piston f, and with it the valve-s'pindlef ,until the plug f meetsthe bottom of the vessel (1, when by the continued downward movement ofthe piston f the valve f is caused to leave its seating and to allow theliquid to pass through the hollow piston-rod and enter the measuringvessel d through the orifices f in the piston-rod. The liquid continuesrising in the vessel d until the pressure of the gas confined above itssurface is equal to the pressure with which the liquid is entering,after which no further movement of the liquid occurs. On returning thevalve to the position shown in Fig. 1 the confined gas is allowed toescape through the hole 0 recess 0 and hole 0 into the arm or bracketa,when the piston f immediately returns to its normal position, openingthe spout-orifice d,and thus allowing the liquid to discharge itselffreely and without shock into a glass or other receptacle held toreceive it.

What I claim, and desire to secure by-Letters Patent, is-

In an apparatus for supplying aerated liquids from bulk on draft, thecombination of a valve-seat having a central longitudinal passage, apassage c ,at an angle thereto and communicating therewith, a hole 0 anda lateral passage 0 with a rotatable controlling-valve having notchesand forced into its seat by pressure of the aerated liquid and having acentral recess, a recess 0 extending through said valve and a curvedrecess 0 in its face, and a hole 0 a spindle provided with hornsengaging said notches in the valve, a seating for the valve-spindle, anoperating-handle on the spindle, a stop on said handle, a sleeve throughwhich the spindle passes and fitted in the end of the valve-body andprevented from rotating therein, a capnot through which the upper end ofthe sleeve projects, said upper end being cut away to provide pointsbetween which thestop on the handle works, and a spring acting to assistthe pressure of the aerated liquid in holding the valve down on itsseating and the valve-spindle up against its seating, all as and for thepurpose specified.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM NICHOLLS.
